Asterisk integration: no such zimlet: ch_bnc_asterisk

Hi,

I'm using the instructions at : Asterisk PBX Integration Zimlet - Browse Files at SourceForge.net
I first tried without the "fix JSP/taglib" then a second time with it.
I'm running a clean install of the 8.04 network edition (vmware appliance on ubuntu 10.04.4 LTS)
When I try to do the initial configuration for that zimlet, I have a "Code:account.NO_SUCH_ZIMLET"
What should I do?
